Garmin Power Cable f/GPSMAP® 7x2, 9x2, 10x2 & 12x2 Series

The Garmin Power Cable for GPSMAP 7x2, 9x2, 10x2 & 12x2 Series is a 6-foot, 8-pin marine power and data cable designed to reliably supply power to compatible Garmin chartplotters while simultaneously enabling NMEA 0183 device integration. This cable connects your primary navigation display to external sensors, autopilot systems, and alarm outputs—critical infrastructure for any vessel relying on networked electronics.

The 6-foot length provides adequate reach from console to battery or power distribution panel without requiring additional adapters or splicing. The 8-pin connector is proprietary to the 7x2, 9x2, 10x2, and 12x2 series GPSMAP units and ensures secure, weatherproof coupling essential in the corrosive marine environment. The dual power/data functionality means a single cable consolidates both electrical supply and NMEA 0183 serial communication, reducing clutter in the helm area and minimizing potential failure points. Marine networks carrying autopilot commands, fish finder data, and alarm status depend on clean electrical contact—oxidation or poor connectivity in saltwater conditions can degrade signal integrity.

This cable is essential for operators who integrate multiple marine systems: those running external lamps or horns triggered by GPSMAP alerts, connecting dedicated transducers, or synchronizing autopilot steering commands across the network. Weekend anglers upgrading from standalone GPS to a networked chartplotter, as well as offshore fishing crews and commercial operators managing complex electronics suites, depend on reliable interconnects. If you own a compatible Garmin GPSMAP unit and are installing new electronics, replacing a damaged cable, or expanding system integration with NMEA-compatible devices, this OEM cable provides genuine Garmin compatibility and assured durability in harsh saltwater conditions.
